About this product
Product information from the supplier.
The Magnetic Torque system represents a pinnacle of attitude control technology for advanced space applications, specifically engineered for satellites and spacecraft operating in Low Earth Orbit (LEO). By strategically interacting with the Earth's natural magnetic field via high-precision magnetorquers, this system provides a sophisticated method for orienting and stabilizing spacecraft without the reliance on traditional consumables.
Designed for maximum reliability and efficiency, our Magnetic Torque solutions eliminate the need for chemical propellants or complex mechanical moving parts. This makes them an ideal choice for small satellites and mission-critical aerospace platforms that demand precision orientation, reduced mass, and high power efficiency, ensuring long-term operational stability in the harsh environment of space.

Frequently Asked Questions
Q: How does the Magnetic Torque system differ from reaction wheels?
While reaction wheels use internal momentum for fast adjustments, Magnetic Torque systems interact with the Earth's magnetic field. They are often used together to "desaturate" reaction wheels without using fuel.
Q: Is the Magnetic Torque system effective in High Earth Orbit (HEO)?
It is most effective in Low Earth Orbit (LEO) where the Earth's magnetic field is strongest. Effectiveness decreases as the distance from the Earth increases.
Q: What are the typical lead times for delivery?
Depending on the model (CG-DJ-CJ series), the supply cycle generally ranges between 4 to 5 months.
Q: Can these systems be customized for specific satellite sizes?
Yes, we offer a range of models from the lightweight CG-DJ-CJ-1 (0.07kg) to the high-output CG-DJ-CJ-100 (4kg) to suit various spacecraft scales.
Q: What is the role of the "Time Constant" in magnetization?
The time constant indicates how quickly the coil can reach its rated magnetic moment or return to its residual state, affecting the responsiveness of the attitude control.
Q: How does power consumption impact satellite battery life?
With power consumption as low as 0.3W to 2.7W, our systems are designed to minimize the drain on the spacecraft's power subsystem, maximizing mission longevity.
